CURLINFO_POSTTRANSFER_TIME_T - Man Page

#include <curl/curl.h>

CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_POSTTRANSFER_TIME_T,
                           curl_off_t *timep);

Pass a pointer to a curl_off_t to receive the time, in microseconds, it took from the start until the last byte is sent by libcurl.

When a redirect is followed, the time from each request is added together.

See also the TIMES overview in the curl_easy_getinfo(3) man page.

This functionality affects all supported protocols

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode res;
    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
    res = curl_easy_perform(curl);
    if(CURLE_OK == res) {
      curl_off_t posttransfer;
      res = curl_easy_getinfo(curl, CURLINFO_POSTTRANSFER_TIME_T,
                              &posttransfer);
      if(CURLE_OK == res) {
        printf("Request sent after: %" CURL_FORMAT_CURL_OFF_T ".%06ld us",
               posttransfer / 1000000, (long)(posttransfer % 1000000));
      }
    }
    /* always cleanup */
    curl_easy_cleanup(curl);
  }
}
